EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 704,552, dated July`15, 1902.

Application led December 6, 1901. Serial No. 84,942. (No model.)

To all wir/0m, it may concern:

Be it known that I, FRANK LIEsKE, a citizen of the United States,residing at Marquette, in the county of Marquette and State of Michigan,have invented a new and useful Extension-Table, of which the followingis a specification.

The invention relates to improvements in extension-tables.

The object of the present invention is to improve the construction ofextension-tables and to provide a simple and comparatively inexpensiveone in which the leaves will be permanently mounted on it and which willbe capable of ready adjustment to provide a table of the desired size.

A further object of the invention is to provide a table of thischaracter in which a large number of leaves may be employed to provide atable of great capacity and which will enable the leaves not in use tobe compactly arranged beneath those in use. y

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended'.

In the drawings, Figure 1 is a perspective view of an extension-tableconstructed in accordance with this invention, the table being extendedand inverted.` Fig. 2 is a side elevation partly in section, the tablebeing folded. Fig. 3 isa detail view of one of the spring` catches forholding the table folded. Fig. 4 is a reverse plan view of a portion ofthe top of the table, illustrating the manner of locking the fixedhorizontal leaves together when the table is folded.

Like numerals of reference designate corresponding parts in allthefigures of the drawings.

1 and 2 designate fixed horizontal leg-receiving leavessecured to theupper ends of end and intermediate legs 3 and 4 and connected by foldingextensible leaves 5 and 6, which are adapted to fold and drop whollybelow the top of the table, as illustrated in Fig. 2 of the drawings.The end legs 3 are preferably arranged in pairs andare connected by atransverse bar 7, and the intermediate leg 4 is arranged at the centerof the leaf 2, as clearly illustrated in Fig. 1 of the drawings. 'lheleaves 5 and G, which are adapted to fold to permit the fixed horizontalleaves 1 and 2 to be brought together to reduce the length of the table,are hinged at their adjacent edges to a connecting strip or section 8,which is interposed between the leaves 5 and 6 when the latter are inahorizontal position and which is arranged below the leaves 5 and 6 whenthe latter are folded. The hinges 9, which connect the leaves 'and 6 tothe strip or section 8, are secured in recesses of the adjacent edges ofthe partsand have their pintles arranged adjacent to the upper face ofthe table-top when the leaves 5 and 6 are in a horizontal position. Theconnecting strip or section also has mounted upon it a pivotedlocking-bar 10, which when the parts are arranged as illustrated in Fig.1 extends entirely across the folding leaves 5 and 6 and is interlockedwith the fixed horizontal leaves 1 and 2, preferably by engaging a cleat1l of the leaf 1 and the top ofthe leg 4 of the section 2, the leg 4being enlarged at the top to provide a shoulder at each side forengagement with lockingebars. Theleaves 5 and 6 are connected with thefixed horizontal leaves 1 and 2 at points between the side edges thereofby hinges 12 and 13, composed of ythree leaves, as shown; but any otherform ofhinge may be employed, if desired. The

central leaf of the hinge 12 is secured to the table-leaf 1 midwaybetween the side edges thereof, and the inner side leaf 14 is secured tothe adjacent folding leaf 5. The other side leaf 15 of the hinge isattached to a folding end leaf 16 of the table-top. This arrangement ofhinges permits the folding end leaf of the table-top and theintermediate folding leaf 5 to swing downward to points beneath thestationary horizontal end leaf 1.

The folding end leaf 16 of the table-top is held in a horizontalposition by a pivoted locking-bar 17, which when the table-leaf 16 is ina horizontal position is adapted to extend over the lower face ofthefxed horizontal leaf 1 to the cleat 1l. The cleat 11 is provided atits ends with recesses toreceive the locking-bars 10 and 17. The centralleaf of the hinge 13 is secured to the lower face of the fixedhorizontal leaf 2 midway between the side edges thereof, and one of theend leaves is secured to the adjacent folding leaf IOO 6 of thetable-top, and the leaf 18, which is secured to the table-leaf 6,permits the latter to swing downward to a point beneath the xedhorizontal leaf 2. This will permit the adjacent 'edges of the leaves 1and 2 to. abut against each other, as shown in Fig. 2, when the table isfolded. The other end leaf 19 of the hinge 13 is fastened to theadjacent leaf 20 of a set of folding extensible leaves similar to theleaves and 6, but arranged between and connecting two intermediate ixedhorizontal leaves 2. The leaves and 21 are connected at their adjacentedges to a strip or section 22 by hinges 23, arranged similar to thesaid hinges 9.

Any nulnber of table-leaves 2 may be employed, and any number of foldingleaves 20 and 21 may be employed for providing extensible connectionsbetween such fixed horizontal leaves 2, and by varying the number of thelatter a table of any desired length may Abe provided. The intermediatelegs, which are centrally secured to the fixed horizontal sections 2,have their enlargements spaced from the said leaves 2 to provide op--posite recesses to receive the locking-bars,

and the section or strip 22 has pivotally mounted on it a locking-bar24, which is adapted to extend across the folding leaves 20 and'21 andengage the intermediate legs 4. In order to facilitate the arrangementof the locking-bars 10 and 24 in alinement with the strips or sections 8and 22, the latter are providedwith stops 25 and 26 to limit the swingof the locking-bars, which are recessed at one end to receive the stops.

yWhen the table is folded, the legs are connected by spring-actuatedcatches 27, pivoted between perforated ears 28 of a bracket or plate 29and adapted to engage a loop or keeper 30. The spring-actuated catch isprovided with a beveled head to enable it to engage the loop or keeperautomatically when the table is folded, and the said head is alsoprovided with a shoulder for engaging the loop or catch. The spring 31is interposed between the inner end of the catch and the bracket orplate, and the said catch is provided with a recess 32 to receive theadjacent portion of the coiled spring, which is secured to the bracketor plate in any suitable manner. The catches and keepers are arrangedcentrally of the table, and those for locking the end blades are mountedon the transverse bars of the same. The leaves are locked againstdisplacement when the table is folded by approximately Lil-shapedlocking devices 33, consisting of a pintle or shank 34 and anapproximately L-shaped arm 35, composed of a long longitudinal portionand a short inwardly-extending transverse portion. The pintle portion ismounted in a suitable bearing-opening of a block 37 and is provided atthe end with a stop 38 to limit its outward movement, the locking devicebeing adapted to be reciprocated transversely of the table to engage itsarm 35 with a socket 39 of a corresponding block 37. The blocks 37 aremounted on the fixed sections 2, and the said locking devices areadapted to extend across the adjacent edges of the fixed horizontalsections, and they are capable of preventing the same from separating.One of the fixed end sections 1 is provided with a single block 40,which has only a bearing-opening, and the other fixed end section isprovided with a block 41, which is provided only with a socket toreceive the engaging arm of the adjacent locking device. The lockingdevices are adapted to be readily drawn outward to release the fixedhorizontal leaves to enable the table to be extended. The folding. endleaves 16 are provided with suitable stops 43 to limit the swing of thelocking-bars 17.

It will be seen that the extension-table is exceedingly simple andinexpensive in construction, that the folding leaves, which are arrangedin sets, are permanently mounted on the table, and that they permit atable of any desired length to be readily constructed, and'they enablethe same to be compactly folded when not in use.

What I claim is-` 1. An extension-table comprising stationary horizontalleaves, legs supporting the same, intermediate folding leaves hinged tothe stationary leaves and adapted to swing inward wholly beneath the topof the table to permit the stationary leaves to be brought together, aconnecting strip or section hinged to the adjacent edges of the foldingleaves, and a locking device supported by the connecting strip orsection and adapted to hold the folding leaves in a horizontal position,substantially as described.

2. An extension table comprising fixed horizontal leaves, intermediatefolding leaves hinged to the fixed leaves and adapted to swing downwardwholly beneath the top of the table, a connecting strip or sectionhinged to the adjacent edges of the folding leaves, and a locking-barmounted on and carried by the connecting strip or section and adapted toextend across the folding leaves to lock the same rigid with the fixedleaves, substantially as described. l

3. An extension table comprising fixed horizontal leaves or sections,legs supporting the same, the intermediate folding leaves hinged to thefixed leaves and arranged to swing downward, the connecting strip orsection hinged to the adjacent edges of the folding leaves, alocking-bar pivoted to the connecting strip or section and arranged toextend across the folding leaves when the latter are arranged inahorizontal position, and means carried by the xed leaves for engagementwith the pivoted locking-bar, substantially as described.

4. An extension-table comprising the fixed horizontal leaf 1, a pair ofend blades snpporting the same,the intermediate xed leaf 2, a centralleg supporting the intermediate leaf and having opposite shouldersspaced from IIO the same to form recesses, a cleat mounted on the iXedsection l, the folding intermediate leaves hinged to the iixed leaves,the connecting strip or section hinged to the adjacent edges of thefolding leaves, and a locking-bar pivoted to the connecting strip orleai` and arranged to engage the cleat, and the central leg,substantially as described.

5. An extension table comprising fixed horizontal leaves, legssupporting the same, folding intermediate leaves, and locking mechanismfor connecting the legs composed of a horizontal loop mounted on oneleg, a vertically-swinging catch pivotally mounted on the opposite legand provided above its pivot with a recess, and a coiled spring locatedin the recess and interposed between the catch and the leg and holdingthe said catch in engagement with the horizontal loop, substantially asdescribed.

6. An extension table comprising xed horizontal leaves, folding leaves,blocks mounted on the fixed leaves, one of the blocks being providedWith a socket, and an approximately U-shaped locking device consistingof an elongated pintle j ournaled on one block and slidably connected tothe same, whereby the locking device is capable of swinginglongitudinally of the table and of sliding transversely of the same, ashort engaging portion for engaging the socket of the other block tolock the table in its folded position, and a connecting portion,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

FRANK LIESKE.
